Abstract
L'électrode positive de l'invention est destinée à une batterie secondaire à électrolyte non aqueux. Cette électrode positive contient une couche de mélange d'électrode positive qui contient à son tour une matière active d'électrode positive, un matériau conducteur et un agent liant. Le matériau conducteur contient à la fois un noir de carbone et des nanotubes de carbone monoparois. L'agent liant contient au moins un élément choisi dans un groupe constitué d'un caoutchouc à teneur en groupe nitrile et d'un dérivé cellulosique.
